This is from the 1890's. The pressures then were the equivalent of the RST shells. So, who ever is saying RST is safe in your barrels is not competent.



This is a burst barrel caused by an obstruction. Please take a good look at the middle finger.



I and many others here shoot damascus barrels.
Almost everyone here shoots vintage guns.
Most all have the common sense to not play Russian Roulette.

If you want the barrels measured again, just say so.
There are many here who have the equipment and willingness to help.
Ask who ever measures the barrels to provide a written chart for each tube.

The best advice so far is to have full length Briley tubes made up in my opinion.
Sleeving the gun will be very expensive.
